T'o all iulzomizi'mdg eoncem:

Be it known th'ELt I, BURNHAJM G. STICK State of New Jersey, have invented cer' tain new and useful Improvements inType writing Machines of which the followingis a specification.

The present invention relates to sounddeadening casings for ty ewrit'ing ma chines, and more particularly'tothe window thereof throu h which the rinting is'v1s1'-; ble to the operator.

In a casing of this cha1*acter,'thetop 1 sordinarilyarohed upward from the rear to accommodate the' carriage of thetypewrit in'g' machine and," to eliminate unnecessary hulk nd weight; it is thence slo ectdown ward and forward to the front of the cas inf; The window has usually heenf'a' fiat wihdow setin this forwardly-sloping"part of the top of the'casin'g; It has been found that lights, when in=certain positions, above the 'typew'riter desk or stand/are objection-'- ah'ly'reflec'ted into the eyes'of the operator by such" a window; and various expedients, such as 1 having the w-indo'w pane angularly adjustable; within nioder'a'te" limits, have heretofore been resorted'to for diversion of such 1 objectionable I reflections. 7

It is anfobject of"thepresentinve'ntion'to' substitute," forthe flat sloping fwindow pa ne'; a windowcompr-ised-of a plurality off-panes set'at anangl' to -one another, and se't at such angles that" no"- properly ositioned light will be objection'ably reflected to the operator.- In the preferred fornrof" the invention, I' provide" a'- 'window with" two such; panes, one a horizontal pan'e, which will cause the rays from a light; over the stand or desk, to be reflected upwarctabov the operators line of visi i; and the 'oth'er'a' vertical pane, which will cause any rays reflectecl there from' to pass below the 'ope'r' ators line" off vision. Either" thevertical orthe horizontal pane may bein the opera; tors line'of vision of'tl1e"platen, and the other pane *will serve to 'assistfin the' il l'umif nation of the interior of the casing; Only the pane which is' in 'th'e o erators line-of vision of the platen eed betra'n'spare'nt'g' the other pane maybe transliicent', an'd,'-if desired, may have a" ground outer surface; that i he can. be bieeian we flec'tion therefrom, regardless of the position" of the lightf;

A further object of the invention iS' -th'e provision of means" whereby the windcw thereof may be interchangeable withthe" ordinar fiat slopi'n v'vinddw; so that one on the other may" in used, according to lighti'ng -conditionsor taste;

A. further object of the invention is the provision of means whereby the window may be 'in'verted, at='will,= in its frame, that isgto's'ay, maybe s'etfso astohe either conve'ii o'r' concavewith respectto the: outside ofth'e cover; In the convex setting of the window, the vertical pane" will ordinarily beat; the front of im tating-and will be the panethro-ugh' which the operator views the printing; In: the concave settinglof the window, onthe other'hand, it willordinarily be the horizontal pane through which the operfa'tonviews'tlie printing; this pane ex-v tending into the casing and connecting with the vertical pane whichdepends into the casing-at the rearof the window-frame.

A further object of the invention is the provision ofnneans whereby" the window may be angularlyfadjusted'to divert reflections of improperly positioned lights; In this connection, it "will he understood that the inventionis not restricted. tba window, the panes ofwhich are set; vertically and horizontally, or'jat righ t angles to each other, or"ev'e'n"toa' window which there are but twopaiie's'i Iii some forms offthe'invention, one of, the panes need not be of elevati on through" theuppe'r part o iffth'e cover of the casing;showinga di'fierentjforni ofaviiidowthere n; r K r p f F-i 'ure las 'aview'in cross-sectional slde el'e ionf upper part of a casin; co-ve'n' embodying; indow'theretor,-

Figure 5 is abroken front view, in crosssection on the line 55 of Figure l, of one end of the casing-cover.

Figure 6 is a View in cross-sectional side elevation, showing the window of the Fig ure 1 style and means whereby the same may be angularly adjusted in the casingcover which supports the same.

Figure 7 is a front view, in cross-section on the line 77 of Figure 6, taken at one end of the cover to show the cover-adjusting means.

Referring to the drawings, the casing is shown as comprising a body-portion 10 and a cover-portion 11 hinged at 12 to the bodyportion. The casing is preferably provided with a sound-deadenin lining (not shown). The position of the p 'laten is indicated in dotted lines at 13, Figure 1, on a carriage 14, also indicated in dotted lines. The top of the cover is provided with an opening18 for a window of glass or other transparent material, through which the operator may observe the printing on the platen 13. The casing-cover is preferably a casting having as part thereof an inwardlydepending rectangular rib 19, which serves as a frame for the window.

In the Figure 1 embodiment of the invention, the window comprises a horizontally disposed pane of glass 20' and a. verticallydisposed pane of glass 21, both supported on triangular metal plates 22, one plate 22 being at each side of the window-frame, as shown in Figure 2. For supporting the plates 22, the ribs 19 at the ends of the window-frame are flanged, as at 23, to serve as seats for the faces of the flange 24 of the plates 22. Clips, in the form of flat metal pieces 25, secured by screws 26 to the cover at the ends of the window-frame,overlie the flanges at the base of the plates 22 and serve to hold the plates to the cover. By loosening or removing the screws 26, the clips 25 may be swung or lifted from the flanges 24 of the plates 22, so as to permit-removal of the window from the frame.- Packing, in the form of astrip of felt 27, is preferably inserted between the flanges 2a of the plates 22 and the flanges 23 on which the same are seated. For attachment of the windowpanes 20 and 21 to their sup-porting plates 22, the latter are provided, at their upper and forward edges, with flanges 28 and 29, respectively. The panes 20 and 21 are set against the flanges 28 and 29, andare secured to their supporting flanges by screws 30. Packing-strips 31 and 32 are preferably inserted between the panes and the flanges, to which they are attached, and the packing 31, as shown in Figure 1, extends across the top of the front pane 21, where the pane 20 overlies the same. For removal or placing of the window, shown. in Figure 1, the screws 30 need not be removed, The supporting plates 22 and the panes 20 and 2'1, secured thereto, are removable or placeab-le as a unit. As shown in Figure 1, the front stretch of the window-frame formed by the head or rib 19 is shaped to provide an inwardly-directed flange 33; and the lower front edge of the vertical pane 21 sets into a packing and sound-deadening strip 34, which serves as a facing for the flanged forward stretch of the window-frame. The rear stretch of the window-frame is likewise provided with a packing and sound-deadening strip 35, against which the rear edge of the horizontal window-pane 20 sets. The lower edge of the pane 21 and the rear edge of the pane 20 are preferably rounded as shown, more effectively to be seated in the packing-strips and close the joints at the edges of the window.

In the embodiment of the invention shown in Figure 1, the operator may observe the.

able reflection will be thrown therefrom to the operator, regardless of the position of the light. lVith the lights in the preferable position, substantially over the typewriting machine, light-rays striking the pane 20, in its Figure 1 horizontal position, would, if the upper surface of the latter were smooth or polished, be reflected upward at such an angle as not to strike the operators eyes. In ordinary cases, therefore, the pane 20 may be made of the usual transparent glass; but, as above noted, it may, where the positions of the lights render it desirable, be made of ground glass or translucent material. Figure 3 shows a transparent pane of 40 set into the opening 18 in the cover 11 of the casing at the same slope as the cover. This Figure 3 angular setting of the pane is not new with the present invention, but is here illustrated to show the interchangeability of the Figure 1 and Figure 3 forms of window when lighting conditions make one 7 or the other form more desirable. As shown in Figure 3, the pane 40 may be set upon the in Figure 3 as over1ying the side ofthepanef 40 in the same manner as in Figure 2' they overlie the fiangesat the'bases24 of the sup porting plates 22.

Figures4 and '5 show' -a modification of the invention in which, as inyFigure ,-'1, the window has a vertical pane and-fa yhorizontat pane In Figure 4, however, the vertical pane/ 41 depends into the casing from the rearof't he window-frame, and the horizontal 'pane 42 fpI'Oj'CtSint/O the casing froml the front of thewindow-frame; The panes 41 and 42 are mounted upon, and supported *by, plates 43' atv the sides --"of the-'window frame The attachmentot the panes 41 and 42 to the plates 43 may =be the same as the attachment of -the panes 20-a nd 21 to the plates 22 in the-f Figure 1- form= of-"the invention; that is: to say,- the plates '43 may, as shown'inFigure- 4, be provided with flanges-28 to which the panes are-attached by screws 30; The plates. 43'j'a-re also provided with flanges' 24, see Figure 5, such as shown at '24- in Figure 2, whereby the windowmaybe-supported'as a unit from the =flanges 23 at the sides :of the Wll'IClOW fI'HIIIGw In the Figures 4 and 5 form of the invention, the oints' are packed, with sound-deadening mater'ial i in the same manner as sho wn-in' Figure 1. The window structure ofjthe Figu'res- 1 :and" 4 inod-ifi'cations, although not vI necessarily identical," is madepreferably-identical, so that there may be interchangeability :between the- Figures 1 and 4- e1nbo diments ofthe invention. To change from the s Figure 1 to the Figureform of the invention; or vice versayit is merely necessary to removev the i-wind'ow, after loosening-or removing the screws v26 swingithe same *over; again seat the flanges 24. and the flanges-23: and reset the fasteners 25' 26. Ob'viously the. arrangement of I the different parts mustbe: such as to give suit; able" clearance-for the carriage 14 when the window-l is in its Figure'4' position Such .a result may be obtainedJby suitable variation in the dimensions of; the-panes 41 1 and i142 and of theframedn which they are held or by arranging'the casingyandi the machine'so that the carriage will beiin a sufficiently low position inthe casing;

' Where the F gures- 1 and 4eforms ofthe invention are to be; interchangeable, however, the. pane-20. should be transparent, because,- in the Figure 4 iform' of'the, invention, it is through the horizontal pane 42 that the op erator observes the .pri-nting on'rthe-platen. In the Figure 4 for1n ofwthdnventiomthe vertical pane .may be. opaque, but zis zprle'ferably transparent; or translucent, better to il= luminate the..- interior': of the; casing. N0 ordinary placement of lights woulda enable rays to be refiectedsfronrthevertical pane 41 in Figure 4, to: the eyes toflthe operator and, with 2tl1eelights arranged in the'preferred positioncovertthemachine;.any;rays reflected from the "horizontal pane 42 would be' L di rected {'upward over the operator in suchdi- V rection asnot to'strike-hiseyesv Whether or not; the Figure '4fwindow -strncture is identi cal with the Figure 1' structure; so as :to' be interchangeable therewith, it may be inter changeable withthe Figure 3 window;

Figures- 6 and 7 'show substantially the Figure 1 window construction together with means whereby the window may be angularly adjusted- In-Figure 6; the rear edge of thehorizontal; pane ha-s a U-shaped 'bi nd'in'g 45 prefer-ably of metal, i secured thereto by screws orriv ets, and having form'ed thereon, and extending longitudinally thereof, at the rear ofthepanea rounded bead 46', which is; setinto a correspondingly ro unde'd recess547 in the edge o-i": the cover 11 which fo'rms'the rear of the window' frame'; Forholding ithe bead 46in the--re cess'-4'7', tliere are provided guards -48 of which there are preferabl'y two, one near-each end" of the window: The guards 48 are-shown as flat metal ipieces se cured =to the cover llg byscrews 49, and adapted, when the screws are-loosened-or removed," to be swung or lifted, s0 '5 that the bead;f46may-be removed from: its seat 4T when it is desired to remove the1 window bodilyfrom the cover Thebead 46 andcits seat 47' being round; permit of 'eas'yangular adj ustmene of the window andthe guards 48 terminate short of the neclc formed by the bead 1'46, fsoras-not tointerferejwith such angul'ar movement of the window Incrder that the window may have ample angular {movement without opening joints in the' casing," the forward reach of thew-in, d w-frame is provided withf a w ide flange 50"curved on ian arc struck from the pivot point at 46, and preferably lined with a strip 51 of 4 sou-nd d'eadening material, such as felt, into which the lower edgeor the verticalpane 21 may set in any angulariposition of the window; Asshown in F-igures 6 and 7, the side reaches of the window-frameialso have" flanges 52; wide; enough an'd' r-of such shape as to prevent opening: of ijoints at the sides of the window, fandxth'e, flanges-52 are also? provided: With'st-rips 5310f felt.

The. panesupportingplate 54, in Figures 6 and-*7, haveflangese-28r and 29, such as shown in Figure- 1, for attachment thereto; of the: windowapanes; but do not require "the flanges a24 for I supporting: or 1 securing the window in position. In the Figu-res 6 and 27 form ofthe. invcntion',:;the e-wi'ndow is sup ported and-secured in position: by; means of ears 55 :projectinge outward jfrom the plates 54.". The ears- 55 are rper forated,. 'asw at" 56, to receive .reduced portions or] neeks' 57,'in adjusting screws 58'; which latter arejthreada; ed into the metal of the. casing=cover-11 :and into lugs z59a-which are cast; on the casing; to provide more amplebearzingsr for.- the screws 68; The: screwsifj58/ Mex" provided: with knurled heads 60, by means of which the same may be turned. The shoulders formed by the reduced portions or necks 57 of the screws 58Vengage the cars 55, to cause the window structure to be lifted or lowered as the screws are turned. The perforations 56 in the ears 55 are of such size as to allow for angular movement of the window structure.

In the structure of Figure 6, as in the structure of Figure 1, the operator will observe the printing on the platen through the vertical, pane 21. In connection with Figure 1, it has been stated that, with the lights in the preferred position, a transparent or polished pane 20 would reflect the rays upward in a direction in Which they would not strike the operators eyes. In the event the lights are not so positioned, but are where a reflection from horizontal pane 20 would annoy the operator, the objectionable reflection may be eliminated by swinging the window angularly, in one or the other direction, by means of the adjusting screws 58 in the manner described.

This application is in the nature of an improvement upon the devices shown in the application of John VValdheim, Serial No. 512,741, filed November 4, 1921, and in my co-pending application, Serial No. 513,001, filed November 5, 1921, and upon the devices shown in the patent granted to said John lValdheim, July 1, 19:24, No. 1,- 499,709. Said l/Valdheim application and patent are in the nature of improvements upon the machine covered by ail-application Serial No. 381,259, filed by me May 1 1, 1920; but the present case contains no claim that could be made in said application No. 381,259.
